Cutter suction dredgers typically utilize two types of dredging pumps: one located in the cabin and one underwater pump mounted on the ladder. When both pumps operate together, they enable extended discharge distances and deeper dredging capabilities.

The combined system achieves dredging depths exceeding 30 meters and total discharge distances ranging from 2000 to 4000 meters.

• Enhanced suction depth and increased output compared to horizontal cabin pumps
• Superior pressure resistance compared to vertical sand pumps
• Lightweight bracket with waterproof oil seal design for optimal underwater operation

• Advanced 3D design technology for optimal performance
• Robust and functional engineering design
• Specialized front liner and impeller design for easy maintenance
• Extended wet parts lifespan for significant cost savings

Zidong high-efficiency horizontal dredge pumps are engineered for heavy-duty applications across multiple industries:

• Mining operations and power sector applications
• River dredging, tailings management, and specialized applications
• Continuous pumping of highly abrasive, high-density sand and gravels
• Port maintenance, watercourse clearing, sand extraction, and lake development
• Land reclamation projects and sediment management
• Slag discharge in iron mines, tailing ponds, and ore dressing facilities
• Metallurgical applications including high-concentration tailing slag and high-temperature iron processing
• Gold washing operations and mineral extraction
• Shallow water zone and swamp operations for environmental and construction projects

Zidong ZN500 underwater sand dredging pumps are successfully deployed in overseas projects, demonstrating reliable performance in demanding marine environments.
